!WARNING: Escaping fluids under pressure can penetrate the skin and cause seri-
ous personal injury. Observe the following precautions to avoid hydraulic hazards:
• Tighten all connections before applying pressure. Relieve pressure before
connecting or disconnecting hoses.
• Check for leaks with a piece of cardboard. Do not use hands!
• Do not exceed working pressure of hydraulic hoses. Visually inspect hoses
regularly and replace if damaged.
5. Run the puller for approximately 1 minute to remove any trapped air and then stop the
hydraulic power source.
!CAUTION: Use a minimum 10 micron nominal filter for proper filtration of the
hydraulic system. Equipment failure could result from improper filtration.
C. POSITION THE FOOT CONTROL VALVE ASSEMBLY
The foot control valve assembly controls the speed and direction of rotation of the cap-
stan. The further the foot pedal is pushed down, the faster the puller turns. To
temporarily
reverse the capstan, the foot pedal can be lifted up.
!NOTE:
Cable must be pulled only while pushing
down
on the foot pedal.
To pull
cable with the capstan rotating the opposite direction, reverse the quick-connect couplings
of the hydraulic hoses on the puller (see previous section).
1. The foot control valve assembly is fitted with an adjustable speed control stop. The
speed control stop relieves operator foot fatigue by limiting the downward travel of the
foot pedal.
Do not force the pedal if it does not move.
Adjust the speed control knob
counterclockwise to increase speed, clockwise to decrease speed. The operator should
now feel the pedal move freely.
2. Position the foot control valve at least 3 to 4 feet (0.9 to 1.2 m) from the capstan’s
feed-off side (figure 3). Position the foot control in the best possible location for
safety and proper operation. Multiple operators may be required for safety or
operational requirements.
3. The manually adjustable pressure relief valve allows a secondary method of controlling
the maximum pulling tension. The relief valve is factory set to release the hydraulic
pressure at approximately 700 pounds (3113 N) of pulling tension while using the
Condux 30 inch (762 mm) diameter capstan. If required, adjust the relief valve to a
20°
